Do I need to spray foam the ceiling of my crawl space to help winterize it?
I have a 600 sq foot cottage and would like to winterize the crawl space. Every winter I have the water turned off to keep the pipes from freezing. The crawlspace is on concrete blocks and a concrete floor. I cannot put a gas furnace in it as it doesn't meet the code---only 30" deep. If I have the spray foam done should that include the ceiling of the crawl space?
I need a solution so I can use the cottage in the winter and keep the pipes from freezing. Any suggestions would really be appreciated. Thank you.
